Renamed generic 'stats' variables to more specific names such as 'domainStats', 'errorStats', 'tldStats', and 'importStats' across controllers and views. This improves code readability and reduces ambiguity when handling different types of statistics in the application.
Enhances the fetch logic to detect and handle non-JSON server responses, providing clearer error messages for PHP errors or session issues. Also adds specific handling for gateway timeouts by retrying the request after 5 seconds.
Introduces error log tracking with new ErrorLog model, controller, views, and migration. Adds admin UI for viewing, resolving, and deleting errors. Implements bulk actions for users and notification groups, refactors domain filtering/pagination, and centralizes admin access checks using Auth::requireAdmin().
Introduces CSRF protection to all sensitive controller actions, integrates configurable CAPTCHA (reCAPTCHA v2/v3, Turnstile) for authentication and registration flows, and centralizes input validation via a new InputValidator helper. Adds new helpers and services for CSRF and CAPTCHA, updates settings and migration for CAPTCHA configuration, and enhances logging and error handling in TLD registry import processes. Also improves validation for user, domain, group, and profile inputs throughout the application.
